  • Enumerate shared folders on Windows with low privileges

    - by Phil Nash
    Using C++ (VS2008) I need to be able to enumerate all shared folders on the current machine and get or construct the local and remote names. We've been using NetShareEnum for this fairly successfully, but have hit a problem where we need to run with a user account with low privileges. To get the local path using NetShareEnum we need to retrieve at least SHARE_INFO_2 structures - but that requires "Administrator, Power User, Print Operator, or Server Operator group membership". I've been trying to use WNetOpenEnum and WNetEnumResource instead but I don't seem to be getting the local name back for that for shares either - and I can't seem to get it to enumerate just local resources - it goes off and finds all shared resources on the local network - which is not an acceptable overhead. So I'd either like help on where I'm going wrong with WNetEnumResource, or a suggestion as to another way of doing this. Any suggestions are much appreciated.

  • Shared library linking and loading in BusyBox 0.61

    - by Alex Marshall
    Does anybody know how the dynamic linking and shared library loading works in BusyBox 0.61 ? I can't seem to find how this is done. There's no 'ld' present on the embedded system I'm dealing with, nor is there an LD_LIBRARY_PATH variable set anywhere. My motivation for this is to be able to create a symlink in the /lib directory to another directory on a different device (with considerably more storage space) for adding in more shared libraries, as the file system that contains /lib is a ramdisk that gets reloaded on startup and is within a few kb of being completely full (so we can't add more libraries to the image, nor can we obtain devices with more memory for the ramdisk)

  • How to create Shared VB Array Initialisors for NerdDinner

    - by David A Gibson
    Hello, I am trying to work my way through the NerdDinner tutorial - and as an exercise I'm converting it to VB as I go. I'm not very far in and after having gotten past the C# Yield statement I'm stuck on Shared VB Array Initialisors. static IDictionary<string, Regex> countryRegex = new Dictionary<string, Regex>() { { "USA", new Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$")}, { "UK", new Regex("(^1300\\d{6}$)|(^1800|1900|1902\\d{6}$)|(^0[2|3|7|8]{1}[0- 9]{8}$)|(^13\\d{4}$)|(^04\\d{2,3}\\d{6}$)")}, { "Netherlands", new Regex("(^\\+[0-9]{2}|^\\+[0- 9]{2}\\(0\\)|^\\(\\+[0-9]{2}\\)\\(0\\)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9\\- \\s]{10}$)")}, Can anyone please help me write this in VB? Public Shared countryRegex As IDictionary(Of String, Regex) = New Dictionary(Of String, Regex)() {("USA", New Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$"))} This code has an error as it does not accept the String and the Regex as an item for the array. Thanks

  • A quick design question about C++ container classes in shared memory

    - by recipriversexclusion
    I am writing a simple wrapper around boost::interprocess's vector container to implement a ring buffer in shared memory (shm) for IPC. Assume that buf is an instance of RingBuffer created in shm. Now, in its ctor, buf itself allocates a private boost::interprocess::vector data member to store values, e.g. m_data. My question is: I think m_data should also be created in shared memory. But it this a necessity? What happens if buf that was created in shm itself, allocates standard memory, i.e. using new. Does this get allocated on the calling process's heap? I don't think buf is allocated there so how come a data member that is private to an object not on a process's heap gets allocated there. I'm confused.

  • Shipping GNU/Linux Firefox plugin with shared libraries (for installation with no root access)

    - by Vi
    The application is a Firefox plugin (loaded from $HOME/.mozilla/plugins), so wrapper script that sets LD_LIBRARY_PATH is not an easy option. RPATH, as far as I know, cannot refer to $HOME and can be only absolue path. Firefox tries to dlopen it's plugin from ~/.mozilla/plugins but fails (because it depends on shared libraries installed somewhere in the user home directory). Modifying Firefox menu item to provide a wrapper (with LD_LIBRARY_PATH) around Firefox is too hacky. What should installer script do (without root access) to make standard firefox load plug-ins that depends on out shared library? Should I just try to make embed everything into that .so to remove dependencies? Should I try to make installer script to finish linking or patch RPATH during the installation phase?

  • Database caching on a shared host

    - by tau
    Anyone have any ideas how to increase MySQL performance on a shared host? My question has less to do with overall database performance and more to do with simply retrieving user-submitted data. Currently my database will create caches at timed intervals, and then the PHP will selectively access the static files it needs. This has given me a noticeable performance boost, but I am worried about a time in which I have so much data that having to read in big files in PHP will actually be slower. I am just looking for ideas for shared hosting solutions; I am not going to get my own server anytime soon. Thanks!

  • Using ECF shared editing with Python

    - by hekevintran
    I can use the shared editing feature of ECF with Java fine perfectly fine. When I try to do it with Python files it also works, but there is no syntax highlighting. I installed PyDev to get syntax highlighting, but then the context menu does not have the "share editor" option. I removed PyDev and the option came back. I installed Dynamic Languages Toolkit in hopes that its Python syntax highlighting was compatible and I got the same effect (context menu lacks the "share editor" option). Is there a way to have a shared editing session with Python files and syntax highlighting?

  • What's a good, threadsafe, way to pass error strings back from a C shared library

    - by PerilousApricot
    Hello, all- I'm writing a C shared library for internal use (I'll be dlopen()'ing it to a c++ application, if that matters). The shared library loads (amongst other things) some java code through a JNI module, which means all manners of nightmare error modes can come out of the JVM that I need to handle intelligently in the application. Additionally, this library needs to be re-entrant. Is there in idiom for passing error strings back in this case, or am I stuck mapping errors to integers and using printfs to debug things? Thanks!

  • How can I change the filename of a shared library after building a program that depends on it?

    - by ZorbaTHut
    I have a program that depends on a shared library it expects to find deep inside a directory structure. I'd like to move that shared library out and into a better place. On OS X, this can be done with install_name_tool. I'm unable to find an equivalent for Linux. For reference, readelf -d myprogram spits out the following paraphrased output: Dynamic section at offset 0x1e9ed4 contains 30 entries: Tag Type Name/Value 0x00000001 (NEEDED) Shared library: [this/is/terrible/library.so] 0x00000001 (NEEDED) Shared library: [libGL.so.1] 0x00000001 (NEEDED) Shared library: [libGLU.so.1] 0x00000001 (NEEDED) Shared library: [libstdc++.so.6] and I would like to errata "this/is/terrible/library.so" to be "shared/library.so". I know about RPATH and it isn't what I'm looking for, I don't need to change search paths globally.

  • Get Function Pointer to function in a shared library I didn't directly load

    - by bdk
    My Linux application (A) links against a Third Party shared Library (B) which I don't have source code to. This library makes use of another third party shared library that I don't have source code to (C). I believe that (B) uses dlopen to access (C) instead of directly linking. My reasoning for this is that 'ldd' on (B) does not show (C) and objdump -X (B) shows references to dlopen/dlclose/dlsym. My requirement is that I need to in my code for (A) get a function pointer to a function foo() located in (C). Normally I'd use dlsym for this, but I need to pass it the handle returned from dlopen which I don't have since (B) does not expose this. - For the larger context: I need to modify the function in (C) such that everytime it calls its helper function bar() (also located in (C)), it also calls a function with the same signature located in (A) with the same parameters (Basically inject my code into the codepath of (C) foo()-bar(). I believe I've found a way to accomplish this using gdb, but in order to port my gdb command list, but I'm stuck on the step of getting the function pointer. I'm also open to alternatives to accomplish the same task rather than the exact problem as stated above Edit: After writing this I realized I can probably just do another dlopen on the file in my code and the symbols returned via dlsym on that handle should be the same as received via the original dlopen, If I'm reading the dlopen man page correctly. However I'm still interested in advice or assistance with the my larger context, If theres a better way to go about this

  • Cutting objects and applying texture to cut. Unity3d/C#

    - by Timothy Williams
    Basically what I'm trying to do is figure out how to calculate realtime cutting of objects, and apply a texture to the cut. I found some good scripts, but most of them have been abandoned and aren't really fully working yet. Applying textures: http://forum.unity3d.com/threads/75949-Mesh-Real-Cutting?highlight=mesh+real+cutting Cutting: http://forum.unity3d.com/threads/78594-Object-Cutter Another (Free) Cutter (Also, I'm not entirely sure how this one will handle cutting complex meshes): http://forum.unity3d.com/threads/69992-fake-slicer?p=449114&viewfull=1#post449114 My plan as of right now is to combine links 1 & 2 or 1 & 3 programming wise. What I'm asking here for is any advice on how to advance (links to asset store packages, or other codes to show how to accomplish something complex like this.)

  • Is it necessary to share every underlying folder in a Dropbox shared folder?

    - by ErnstvdS
    I have one Dropbox (I suppose) shared between my business account / PC and my wife's account / PC running Windows XP and a laptop with Windows 7. I created a folder and shared this one with both (or three) accounts. I created an underlying folder (no need to share, says the help) but it is not visible on the other PCs, so I've shared it to both accounts. Is this sharing necessary for every simple new folder?

  • Help with POCO library (Shared memory)

    - by sevaxx
    I was advised to use the POCO library for inter-process communication (IPC). Looks like a powerful library and there is some documentation in the code, but I would prefer a working example , since I am not very familiar with the IPC stuff. I 've been searching for some time now and I'm out of luck. If anyone has used POCO Shared Memory successfully in the past, I would love to see some sample code !

  • Returning a shared library symbol table

    - by joemoe
    For instance: void* sdl_library = dlopen("libSDL.so", RTLD_LAZY); void* initializer = dlsym(sdl_library,"SDL_Init"); Assuming no errors, initializer will point to the function SD_Init in the shared library libSDK.so. However this requires knowing the symbol "SDL_Init" exists. Is it possibly to query a library for all its symbols? Eg, in this case it would return SDL_Init, the function pointer, and any other symbols exported by libSDL.so.

  • Basic shared memory program in C

    - by nicopuri
    Hi, I want to make a basic chat application in C using Shared memory. I am working in Linux. The application consist in writing the client and the server can read, and if the server write the client can read the message. I tried to do this, but I can't achieve the communication between client and server. The code is the following: Server.c int main(int argc, char **argv) { char *msg; static char buf[SIZE]; int n; msg = getmem(); memset(msg, 0, SIZE); initmutex(); while ( true ) { if( (n = read(0, buf, sizeof buf)) 0 ) { enter(); sprintf(msg, "%.*s", n, buf); printf("Servidor escribe: %s", msg); leave(); }else{ enter(); if ( strcmp(buf, msg) ) { printf("Servidor lee: %s", msg); strcpy(buf, msg); } leave(); sleep(1); } } return 0; } Client.c int main(int argc, char **argv) { char *msg; static char buf[SIZE-1]; int n; msg = getmem(); initmutex(); while(true) { if ( (n = read(0, buf, sizeof buf)) 0 ) { enter(); sprintf(msg, "%.*s", n, buf); printf("Cliente escribe: %s", msg); leave(); }else{ enter(); if ( strcmp(buf, msg) ) { printf("Cliente lee: %s", msg); strcpy(buf, msg); } leave(); sleep(1); } } printf("Cliente termina\n"); return 0; } The shared memory module is the folowing: #include "common.h" void fatal(char *s) { perror(s); exit(1); } char * getmem(void) { int fd; char *mem; if ( (fd = shm_open("/message", O_RDWR|O_CREAT, 0666)) == -1 ) fatal("sh_open"); ftruncate(fd, SIZE); if ( !(mem = mmap(NULL, SIZE, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0)) ) fatal("mmap"); close(fd); return mem; } static sem_t *sd; void initmutex(void) { if ( !(sd = sem_open("/mutex", O_RDWR|O_CREAT, 0666, 1)) ) fatal("sem_open"); } void enter(void) { sem_wait(sd); } void leave(void) { sem_post(sd); }

  • Retaining Managed objects - more general retaining objects

    - by Luuk D. Jansen
    A quick question regarding Managed Objects. I created an Array with Managed Objects (in Object 1: TableViewConbtroller), and pass one of those objects to another class/object (object 2: TableCell). The original array should still be retained in the original caller class. Then Object 2 is released, does that mean that that particular item in the array is released as well, as the reference to it in Object 2 was released? I am trying to better understand how to work with ManagedObjects as I get 'Object was released' errors. [EDIT] After some experimenting I came across the following scenario: I have the main AppDelegate. In a different class I create an AppDelegate to obtain the ManagedObjectContext. appDelegate = (iDomsAppDelegate *)[[UIApplication sharedApplication] delegate]; [self setContext:[appDelegate managedObjectContext]]; When the class is finished, and I release it, the variable in the class 'appDelegate' is also released. But then the ManagedObjectContext is closed, and obvious any future attempt to use it will cause a crash. So should I leave the appDelegate unreleased? This comes to the same question as the above about when and how to release in those situations where an objects is used from another class. I think a way of putting it is, how to know when you own an object and when not.

  • CUDA: When to use shared memory and when to rely on L1 caching?

    - by Roger Dahl
    After Compute Capability 2.0 (Fermi) was released, I've wondered if there are any use cases left for shared memory. That is, when is it better to use shared memory than just let L1 perform its magic in the background? Is shared memory simply there to let algorithms designed for CC < 2.0 run efficiently without modifications? To collaborate via shared memory, threads in a block write to shared memory and synchronize with __syncthreads(). Why not simply write to global memory (through L1), and synchronize with __threadfence_block()? The latter option should be easier to implement since it doesn't have to relate to two different locations of values, and it should be faster because there is no explicit copying from global to shared memory. Since the data gets cached in L1, threads don't have to wait for data to actually make it all the way out to global memory. With shared memory, one is guaranteed that a value that was put there remains there throughout the duration of the block. This is as opposed to values in L1, which get evicted if they are not used often enough. Are there any cases where it's better too cache such rarely used data in shared memory than to let the L1 manage them based on the usage pattern that the algorithm actually has?

  • Should these concerns be separated into separate objects?

    - by Lewis Bassett
    I have objects which implement the interface BroadcastInterface, which represents a message that is to be broadcast to all users of a particular group. It has a setter and getter method for the Subject and Body properties, and an addRecipientRole() method, which takes a given role and finds the contact token (e.g., an email address) for each user in the role and stores it. It then has a getContactTokens() method. BroadcastInterface objects are passed to an object that implements BroadcasterInterface. These objects are responsible for broadcasting a passed BroadcastInterface object. For example, an EmailBroadcaster implementation of the BroadcasterInterface will take EmailBroadcast objects and use the mailer services to email them out. Now, depending on what BroadcasterInterface implementation is used to broadcast, a different implementation of BroadcastInterface is used by client code. The Single Responsibility Principle seems to suggest that I should have a separate BroadcastFactory object, for creating BroadcastInterface objects, depending on what BroadcasterInterface implementation is used, as creating the BroadcastInterface object is a different responsibility to broadcasting them. But the class used for creating BroadcastInterface objects depends on what implementation of BroadcasterInterface is used to broadcast them. I think, because the knowledge of what method is used to send the broadcasts should only be configured once, the BroadcasterInterface object should be responsible for providing new BroadcastInterface objects. Does the responsibility of “creating and broadcasting objects that implement the BroadcastInterface interface” violate the Single Responsibility Principle? (Because the contact token for sending the broadcast out to the users will differ depending on the way it is broadcasted, I need different broadcast classes—though client code will not be able to tell the difference.)

  • Split NSData objects into other NSData objects with a given size

    - by Cedric Vandendriessche
    I'm having an NSData object of approximately 1000kb big. Now I want to transfer this via bluetooth. This would be better if I have let's say 10 objects of 100kb. It comes to mind that I should use the -subdataWithRange: method of NSData. I haven't really worked with NSRange. Well I know how it works, but then to read from a given location with the length: 'to end of file'... I've no idea how to do that. Some code on how to split this into multiple 100kb NSData objects would really help me out here. (it probably involves the length method to see how many objects should be made..?) Thank you in advance.
